The Orville, "Lasting Impressions"
The show, a satire/homage of Star Trek, takes place in the 2400s. Archeologists discover a time capsule from 2015, in which a cell phone is discovered. They manage to access it, and a video from the owner, Laura, pops up.
Gordon, the ship's pilot, has been rather unsuccessful with the ladies, and finds himself drawn to Laura's video. He uses her cell phone, which is full of information (texts, videos, whatnot), to create a holographic simulation of Laura and her life.
At the time of the program's opening, Laura has broken up with her long-time boyfriend, Greg. Gordon is rather taken with her, and keeps reentering the program (to the crew's worry).
She initially tells him that she is a saleswoman at Macy's, but dreams of making it as a singer. He goes to hear her soulfully strum and croon in a bar, and, quite typically, falls in love with her.
However, the program is operating on the details of her phone, and she gently explains to him that she has gotten back together with Greg.
Gordon can't bear to let her go, and tells the computer to delete Greg from the program.
However, the next time he enters the program, Laura is not the same. She briskly discusses pursuit of a promotion, and when asked about her singing, scoffs that no way could she perform in public.
Greg was the one who encouraged her to take her singing to another level. No Greg, no Laura that Gordon fell in love with.
Commander Grayson explains to Gordon that we are born blank slates, and we become who we are by our relationships. I still think there is a good chunk of nature involved, but it is true to some extent.
I know I wasn't the same person at 31 as I was at 19, and in my almost two years of marriage and becoming a mother, I've probably changed some more.
It also made me think on what sort of influence I have been on others. It's rather daunting, that responsibility.
